Buffering Explained

There are a lot of misconceptions in the streaming world about what buffering is, what causes it, why it happens and how to help avoid it. So we wanted to write an article addressing some of the causes of buffering and how to help minimize it, Please note that I did not say eliminate it as this is impossible.

But before we get into the buffering discussion I want to explain a little bit of how streaming actually works and explain what is happening behind the scenes when you click on something to stream.

So let’s go through what happens when you click on a link. When you click on a link in any program a script (Computer Code) connects your internet connection to the URL address of where that stream is housed. It can take a second or two for your internet and this URL address to be paired up and for data to begin to flow into your device. In most cases it takes a few seconds for the full amount of data the server you are connected to, to begin being transferred to your internet connection. This is why many streaming services like Netflix and Hulu will start off a video in low quality. Then once the full flow of data has begun they will switch to a higher resolution. This is done so that the stream will start faster and as you receive more data it will switch to high quality.

What causes buffering while streaming?

I have read some very interesting theories and ideas on as to why buffering happens. From people thinking that the graphics card can’t handle the stream, the processor is working too hard. As complicated as people want to make buffering issues out to be, it is actually very simple. There are really only two variables that can cause buffering while streaming.

Your Internet Speed and your Router

The first and usually most overlooked reason that buffering occurs is your own internet speed. Many users try to skimp out on upgrading their internet speed. If you are going to stream your video content you need fast internet. While you can get away with 10 Mbps down for most streams, this is really the absolute minimum speed needed for a good streaming experience. When you take into account speed lost through Wi-Fi (Usually much more than you think,) other devices in your house using bandwidth and fluctuations in the internet speed you are actually getting from your provider you can see how 10 Mbps can turn to 5 or below very quickly.

What is the recommend internet speed for streaming? This is a personal preference but we recommend for an optimal streaming experience you should have 25 Mbps or higher.

There are also several other factors that can affect your own internet speeds. The most common negative factor is Wifi. Wifi is extremely convenient for connecting lots of devices to the internet without having to connect them with a wire. With this convenience comes a downside. Wifi signal fluctuates up and down very often which can lead to buffering.

I cannot stress enough how quickly Wifi signal and speeds degrade over distance and through obstacles like walls. People are under the impression that if they are getting a wifi signal to a device that the device is getting the same amount of bandwidth as they pay for.

I have 200 Mbps down at my house and about 15 feet from my router through one glass door I get about 30 Mbps down to my Google Pixel XL. This goes to show how much wifi can degrade over distance and obstacles.

Another huge factor with your internet speed is who else is using it and what are they doing. If you have 10 Mbps down and a family member is downloading a bunch of stuff and another family member is playing an online game then there is a strong chance your video content is going to buffer.

Another great tip to help increase your speed is to reset your router once a week. Your internet provider spent time and money finding a router that they can give you that works just enough to provide a decent signal. They skimped and penny pinched as much as they could to save themselves money. So your stock router is not of the highest quality. With that being said, over time these routers degrade in the speed they are able to broadcast. By simply unplugging the router for 30 seconds and then plugging it back in we have seen many customers internet speed double. If you haven’t reset your router in a long time or forever it is a great idea to do this.

So to summarize your internet speed and how it effects buffering while streaming.

  • Minimum of 10 Mbps Down, while the preferred speed is around 25 Mbps Down.
  • Connecting your unit to the internet via an Ethernet cable is ideal
  • If you must use Wifi, make sure the unit is very close to the router (15 feet or under is ideal)
  • Make sure you have reset your router recently.
  • Keep in mind what others in your household are doing on the internet. If they are doing anything bandwidth intensive it can affect your streaming.

So let’s get into the second source of buffering while streaming. The second half of all of your video streams is the stream sources ability to give you data. You can have 1,000 Mbps down and be hardwired via Ethernet, but if the stream source cannot give you enough data you will get buffering. This a fact that most people do not understand. Take as an example, you are browsing the internet on a fast PC with good internet connection. You click on a website link and the site is very slow to load, you click on another link within the same site and it also loads very slowly. In this scenario your computer is working fine, your internet speed is fast, so why is the website loading slowly? Your computer? Internet connection? Graphics card? Operating system? It is none of these. What is causing the website to load slowly is the server it is using to deliver data for users to view its website. This server is having at least one of many possible issues. It could be overloaded with users, It could have its main internet connection lost and is using a backup internet connection, It could have had a physical hardware failure, one of the many servers it needs to pass through to get to your internet connection is down. These are just a few of the issues a server may encounter that will cause it not to be able to give out enough data to load a website or video stream.

Video content files are stored on servers. These servers have a limit in how much data they can transmit out to people. When these servers reach a level of users they get overloaded and are not able to give out as much data as may be needed for an end user to stream a file with no buffering.

Servers are not cheap to buy, rent or operate. Streams come from all over the world. Some are from multibillion dollar companies with massive data centers, some are from smaller operations and some come from free public servers that limit amounts of data and speeds. The long story short is that sometimes servers get overloaded, fail or go down.

So let’s sum up some of the misconceptions about buffering in while streaming.

  • Buffering has nothing to do with your units Processor speed, Graphics processing power or RAM
  • Buffering has nothing to do with your hardware

 What causes buffering?

  • Slow internet speeds on the users end
  • Wifi signal being weak and or degraded by distance or having to go through walls or other obstacles
  • Other users on your internet network hogging bandwidth
  • The stream sources server being overloaded with too many users
  • The stream sources server having internet issues
  • Your internet provider having fluctuations in their internet service

How to minimize buffering while streaming

  • Have at least 10 Mbps actually getting to the unit. 25 Mbps is preferred
  • Hardwire your unit directly to the internet via an Ethernet cable
  • Reset your router once a week
  • Pause a stream for a minute or two to allow it to build up some data

While most of the streams that you click on will work with no problems at all, you are going to encounter streams that just can’t give you enough data for whatever reason. You can have 1,000 Mbps and be hardwired and you will still have links that won’t stream without buffering. It has nothing to do with your hardware or the program you are using. It is just because the server can’t give you enough data.

If you encounter a stream that isn’t playing smoothly, stop the stream and choose another one. It is that simple.

I wish we could tell you that every link will work and every stream will play flawlessly with zero buffering, but we cannot.

So follow all of the steps to help minimize buffering while streaming and you will have a much better experience.


Wi-Fi Troubleshooting Guide

Enter the correct name for your wireless network

Selecting the wrong wireless network name will cause your wireless network connection to fail. If you are not certain that your SkyStream device is connected to the correct network Read Below.

When connecting your SkyStream device to your home wireless network, you will need to select the name of the wireless network. The SkyStream device scans all available networks and presents a list that is ordered by the strength of the wireless signal.

The wireless network name, sometimes called the SSID, is either the default name that was set by your ISP or router manufacturer, or the name you chose when you set up your wireless network.

How to find your wireless network name

  • Check to see which network your computer or mobile device is connected to. The SkyStream device will connect to the same network.
  • If you cannot remember the name of your wireless network, go to the support sites for your internet service provider or router manufacturer. Also, sometimes the default name is listed on the bottom of the router. 

How to get your wireless password

  • Enter the same wireless password that you use to connect your computer or mobile device to your home network.
  • If you have forgotten the password, go the support sites for your internet service provider or router manufacturer. They will be able to suggest the specific methods for their products to recover the password or reset it. Sometimes the default password is listed on the bottom of the router.

Tips for entering passwords

  • Passwords are case sensitive – Click the  on the on-screen keyboard to enter a capital letter.
  • You must enter the password exactly as it was set. This includes and Capital letters Symbols or Numbers.

Enter the password correctly

If you believe you know your wireless password, but it is not working, try re-entering it. It is easy to make a mistake entering your password, and remember that network passwords are case sensitive.

  1. Check to see that your router is working properly.Using your computer or mobile device, connect to your home network and try accessing the internet by launching a public website like google.com. If you can connect to the internet from another device, your router is successfully providing internet access and you can move to the next step. If you are unable to connect to the internet, try restarting your router (Tips below) before contacting your ISP.
  2. Improve the wireless signal strength. If your password is correct and other devices can access the router, but your SkyStream device is still failing to connect to your wireless network, the most likely problem is the strength of the wireless signal. The wireless signal gets weaker the farther your SkyStream device is from your router, and with more obstacles (like walls and cabinets) between your router and your SkyStream device.
  • If you can move them closer, the signal will get stronger.
  • If you can move them so there are fewer objects and walls between them, the signal will get stronger
  • Perhaps you can try moving the Skystream device closer temporarily, so as to verify that the signal strength is the problem.
  • Try re-orienting the router’s antennas
  • Try moving either your router or the Skystream device. Sometimes just a few inches or feet can make a difference.
  • Try moving your router and Skystream device higher up.
  • If your router or the Skystream device is in a cabinet, take it out.
  • If the TV is between the Skystream device and the router, try
  • Moving the Skystream device so that the TV is not blocking the wireless signal.

 If the wireless signal is still not strong enough, here are additional options:

  • Purchase a new wireless router that provides a stronger signal, or has more reliable software. Routers do vary considerably in their quality – so read the online reviews.
  • There are more advanced home network options, such as range extenders, “mesh network” routers, or powerline extenders (Sold at www.skystreamx.com) which can increase wireless coverage within your house.
  • Is Ethernet an option? The Skystream TWO has an Ethernet port on the back of the device. A hardwired connection will almost always provide faster more reliable internet speeds. Or Ethernet might be a temporary solution to verify that the wireless connection is your real problem.
  • Move the Skystream TWO to a different TV that is closer to your wireless router
  1. Restart your SkyStream device and your router. 
    • Unplug the SkyStream device from the power source, wait a few moments, and then plug it back in.
    • To restart your router, check the instructions from your ISP or router vendor. In some cases, you can simply unplug it and plug it back in, and in other cases it may require pressing a reset button on the device.
Note: It will take a few minutes before both devices have restarted.

Internet Trouble Shooting

There are many factors that come into play on a home network. This section will cover some remedies to common home networking problems. We do recommend that the SkystreamX unit is receiving 10 Mbps or 10,000 Kbps of download speed to operate properly.

  1. Rebooting your Modem – Modems are just like computers. Over time they slow down and need to be reset. We recommend resetting your router at least once a month to ensure you are getting proper speed being fed into your home network. To reset your Modem, simply unplug it from its power source for 30 seconds, plug it back in and let it reboot.
  2. Wifi Distance – Wifi signals are greatly reduced over distance and through obstacles and walls. If you are experiencing slow speeds using Wifi we highly suggest moving the wireless router closer to your SkystreamX unit. We also always recommend  a hardwired ethernet connection over Wifi as it is more stable and provides the maximum internet speed to the unit.

If you are having trouble connecting your internet to the Skystream Android TV Box, please watch the videos above for instructions on how to connect the unit to the internet.

Random Notification Sounds

If you have signed into any email programs or social media applications, you can go to settings, apps, scroll down to the app and click on it. Then scroll down and turn off the notifications.

Low volume on certain streams

If different streams have different volume levels do not worry, this is completely normal. Each stream is created by a different person. Different people record the streams with different volume levels. If you find a stream that has a low or high volume level simply use the volume button on your Skystreamx remote to raise or lower the volume to a desired level.

Low Volume

If you are experiencing low volume on your Skystream Android TV Box please follow these steps to raise the volume level.

  1. Using the Skystream remote control, press the volume up button until the volume is at the highest level. If you see a sound icon with an X through it press the mute button to unmute.
  2. Using your TV or sound system remote control, turn the volume up to your desired level.

Connecting to a Sound System

There are three ways that you can connect your SkystreamX Android TV Box to an external sound system.

Method 1 (Suggested) – Almost all TV’s have an Audio out port. Some TV’s have a red & white component output and some have an HDMI or SPDIF (Optical Audio) output. Whatever output method your TV has, we recommend connecting the audio out to your sound system. With this configuration anything that is being displayed on your TV will have it’s sound sent directly to the sound system. This eliminates having to change the audio channels on your sound system for different devices.

HDMI Pass through

HDMI pass through is a feature on some sound systems. This feature allows you to feed the HDMI Audio & Video signal directly to the sound system and then have the sound system feed the video back to the TV. If your Sound system has HDMI pass through please follow the instructions on how to connect and enable it.

  1. Connect the HDMI cable from the Skystream to the pass through port on your sound system. With a second HDMI cable connect the HDMI pass through out to your TV.
  2. From your Skystreams home screen click on settings, click on Advanced.
  3. Click on Digital Audio auto-detection to turn it off.
  4. Click on Digital Audio Output.
  5. Click on HDMI Passthrough to turn it on.
  6. Turn the volume all the way up using your Skystream remote control. Adjust the audio level using your sound systems remote control.


SPDIF (Optical Audio) Pass through

SPDIF or Optical Audio is an option to play the sound from your SkystreamX to an external sound system or sound bar. Enabling this feature will allow you to push the sound from your Skystream to a sound bar using an optical audio / SPDIF cable.

  1. Plug an optical audio cord into the port on the back of your SkystreamX and plug the other end into the optical audio port on your sound bar or sound system.
  2. From your Skystreams home screen click on settings, click on Advanced.
  3. Click on Digital Audio auto-detection to turn it off.
  4. Click on Digital Audio Output.
  5. Click on SPDIF Passthrough to turn it on.
  6. Turn the volume all the way up using your Skystream remote control. Adjust the audio level using your sound systems remote control.



No Volume

If you are not getting volume please follow the below listed steps.

1. TV Remote – Press the mute button to make sure the TV is not muted. Now turn the volume all the way up.

2. Skystrem Remote – Press the mute button to make sure the TV is not muted. Now turn the volume all the way up.

3. If the first two steps do not work, please try pressing the F8 key on your keyboard.

This should fix the volume issue you are having.

Video Cuts in and out for a few seconds

That is normally caused by a bad HDMI cable or the cable not being fully seated in the port. We would make sure that both ends of the HDMI cable are fully seated. If the screen is still blinking occasionally We would try a different HDMI cable.

No display at all on TV

If you are not seeing any display at all on your TV from the Skystream unit, please follow the troubleshooting steps below.

  1. Make sure that the Skystream unit is plugged in and showing a light on the front of it. If there is no LED the unit is not on.
  2. If the unit is on and displaying a light on the front, check to make sure that the HDMI cable is plugged into the Skystream unit and an HDMI port on your TV.
  3. Using your TV remote press the input or source button to change the input source so that it is showing the video from the HDMI port that the Skystream is plugged into.
  4. If none of these options work, test a different HDMI cable to see if the HDMI was not working properly.
  5. If you have done all of these steps, tested a different HDMI cable and are still not seeing any video display from the Skystream unit please give us a call at 888-963-9105
